horizon-client, horizon-world and horizon-protocol each had an example named `probe`. Cargo copies every crate's examples into one <profile>/examples/ directory, so parallel parity harnesses sharing a target dir could run another crate's probe (CI parity run 40055656303: command_parse ran the horizon-world dispatcher). The examples are now client_probe, world_probe and protocol_probe ([[example]] in each Cargo.toml; the files stay where they are), and every harness builds and runs its own crate's name. tools/parity.py recognises the new names when it counts the probes a harness ran, and renames the old `probe` in recorded artifacts to the crate's target (from the record's -p, else its probe sources), so the prebuild still builds them instead of dropping them as unknown.

"""Compare the world border as the client shows it with vanilla 26.3.
|
|
|
|
The Java oracle (VanillaWorldBorderRenderOracle) drives a vanilla WorldBorder
|
|
through each case's size changes (static, growing, shrinking), centre and
|
|
warning changes and ticks, and for every frame runs WorldBorderRenderer's
|
|
extract, prepare (the cached wall vertex buffer), prepareDynamicTransforms
|
|
(colour, model offset, scrolling texture) and draw (which walls), and
|
|
Hud.extractVignette (the red warning vignette colour). `examples/
|
|
world_border_render_fixture` replays the same cases with `horizon_client::
|
|
worldborder`, `border_render` and `hud_overlays::vignette`; every value must agree
|
|
bit for bit.
